Question: Was Mrs. White in love with Wadsworth? She seemed to be getting rather close to him in the beginning of the film (i.e., giving him a hanky when he's crying about his wife, playing with his tie and being flirtatious when he won't let her outside), but then seems to turn a 180 and not really like him. Why?
Answer: No, Mrs. White was not in love with Wadsworth. She may have been slightly physically attracted to him at the time of the "hanky incident", but it is more likely that she only felt sympathy for this poor man. As for the playing with the tie incident, she only did that so he would let her out.
